The BP Sensor: A Proven Approach For Measuring In-Situ Ice Stresses
Background
- developed in the early 1980's by British Petroleum Ltd. after extensive research
- first used in 1984 for in-situ sea ice stress measurements at Katie's Floeberg, Alaska
- manufacturing license acquired by BMT Fleet Technology from BP in 1990
- over 200 BP Sensors built by BMT
- used for sea ice stress measurements in the Canadian Beaufort Sea, the Labrador coast, and Spitzbergen (1989 - 2005), by BMT and others
- used for measuring freshwater ice loads at Hydro-Electric Dams (1991 - 2008) by BMT
Sensor Development Process
The BP ice stressmeter was developed in 1984 in response to BP's need for a sensor which could accurately measure in-plane stresses in first- and multi-year sea ice, and which could be easily used in the field. This technology was required to support BP's programs related to ice loads on offshore structures. Cold room tests were conducted by BP to develop and test the sensor. The sensor was found to have an inclusion factor very close to unity.
